In addition to the regular build-your-own pizzas, Papa John’s also offers a number of specialty pizzas, from The Works to Garden Fresh to Hawaiian BBQ Chicken. They sound delicious, but are they actually a good deal? In this lesson we’ll write & evaluate expressions to calculate how much it would cost to build each specialty pizza topping-by-topping. We’ll then calculate the savings two ways—in dollars and as a percent—to determine whether specialty pizzas are really worth it. Is it smart to always “go big?” That’s what we’ll find out.
